[mgp-users 00725] Solaris, subscripts

Hi MGP folks:

I have two questions:

(1) Is there an easy way to do subscripts in ordinary text? I just need it 
so that lines like 
 
    Molecules include H2O, O3 and H2SO4

look prettier. I know that one can use various magic tricks to insert 
LaTeX equations into mgp, but that isn't really what I want here as it
seems an over-kill solution and you can't put the resulting equation in
the middle of a regular mgp line.

(2) Is it possible to build mgp (1.08a) on Sparc/Solaris boxes? I have
tried and got an error like this:

"mgp.c", line 1131: cannot recover from previous errors

Sun's standard header files seem to contain definitions for sigset_t so I
imagine that one of those -Dfoobar options has got set wrong. 

I have STFW and had a look at the archive of this list at 
http://www.csl.sony.co.jp/person/nishida/magicpoint.html, but I can't find
any pertinent Solaris-related instructions. I have also downloaded the
current developer snapshot and the same thing happens with it.

Any ideas much appreciated!

Hugh
